[0029] Please refer to Figures 1 to 8 The present invention provides a low-voltage circuit breaker grounding wire quick access auxiliary connector, comprising: a connector body 100, the connector body 100 is used to be electrically connected to an external grounding component, the connector body 100 is provided with a first connection hole 110, the first connection hole 110 is used to be inserted and connected with a rod 3 to be grounded; a locking rod 200, at least part of the locking rod 200 is movably inserted into the connector body 100, the locking rod 200 is rotatably arranged around the axis of the locking rod 200, so that the locking rod 200 moves along the axial direction of the locking rod 200 toward the direction close to the first connection hole 110, so that the locking rod 200 abuts against the rod 3 to be grounded; a detection alarm component 300, the detection alarm component 300 is connected to the connector body 100, and the detection alarm component 300 is used to detect the real-time voltage of the rod 3 to be grounded, so that when the real-time voltage is greater than the safety voltage, the detection alarm component 300 issues an alarm.

[0030] The low-voltage circuit breaker grounding wire quick access auxiliary connector of the present invention includes a connector body 100, a locking rod 200 and a detection alarm 300. The locking rod 200 moves along the axial direction of the locking rod 200 toward the direction close to the first connection hole 110 to abut against the rod 3 to be grounded, so as to prevent the rod 3 to be grounded from rotating and causing the rod 3 to be grounded to fall out of the first connection hole 110, thereby ensuring that the rod 3 to be grounded and the connector body 100 are fully electrically connected, thereby ensuring that the rod 3 to be grounded and the external grounding component are electrically connected, and avoiding the rod 3 to be grounded from having grounding failure, thereby solving the problem of low-voltage circuit breakers in the prior art being prone to grounding failure. At the same time, the detection alarm 300 detects the real-time voltage of the rod 3 to be grounded without contacting the rod 3 to be grounded, and issues an alarm when the real-time voltage is detected to be greater than the safety voltage, thereby preventing the connector body 100 from being electrically connected to the charged rod 3 to be grounded, and avoiding safety accidents.

[0031] Specifically, the grounding rod 3 is electrically connected to the connection terminal of the low voltage circuit breaker.

[0032] Specifically, the detection alarm 300 is composed of a transistor, a buzzer, an LED, an induction coil probe, and a lithium battery. When the detection alarm 300 is close to the grounding pole 3 whose real-time voltage is greater than the safety voltage, there is a magnetic field generated by the current in the grounding pole 3 around the induction coil probe, and the induction coil probe will cut the magnetic flux lines to generate current. The induced current signal Ib passes through the base of the transistor, flows through the emitter, and amplifies the electromagnetic induction current signal by Ib×(1+β) times, and amplifies the signal three times through three transistors. The buzzer and LED that receive the electromagnetic induction current signal start to work, the buzzer sounds an alarm, and the LED flashes to remind the user.

[0033] Specifically, the safety voltage is 36V.

[0034] Specifically, the total length of the low-voltage circuit breaker grounding wire quick access auxiliary connector of the present invention is 23 cm, which greatly saves installation space. By adjusting the installation angle, the low-voltage circuit breaker grounding wire quick access auxiliary connector of the present invention can be installed in a relatively narrow distribution cabinet.

[0035] Specifically, the connector body 100 can be subdivided into three types of replaceable metal head parts: large, medium and small. Different connector bodies 100 can be replaced according to the size of the low-voltage circuit breaker terminal nut and the different phase-to-phase spacing widths of the low-voltage circuit breaker, so that the low-voltage circuit breaker grounding wire quick access auxiliary connector of the present invention is suitable for all low-voltage circuit breakers with a rated current carrying capacity between 120A and 800A, solving the problem of limited application scenarios of existing low-voltage grounding wire clamp adaptation.

[0036] In this embodiment, a through hole 203 extending along the extension direction of the locking rod 200 is provided in the joint body 100, and the locking rod 200 can be movably penetrated in the through hole 203, and the through hole 203 is connected to the first connecting hole 110; wherein, the extension direction of the first connecting hole 110 intersects with the extension direction of the through hole 203.

[0037] Specifically, the through hole 203 is used to accommodate the locking rod 200 , so that the end of the locking rod 200 passes through the through hole 203 and enters the first connecting hole 110 , ensuring that the locking rod 200 can abut against the grounding rod 3 located in the first connecting hole 110 .

[0038] In this embodiment, the low-voltage circuit breaker grounding wire quick access auxiliary connector also includes a grounding shaft 400, which is electrically connected to an external grounding component. A second connecting hole 120 is provided on the circumferential side wall of the connector body 100, and the second connecting hole 120 is connected to the first connecting hole 110. The grounding shaft 400 can be movably inserted into the second connecting hole 120 along the extension direction of the second connecting hole 120 so that the grounding shaft 400 abuts against the locking rod 200.

[0039] Specifically, the connector body 100 is electrically connected to the external grounding component by the grounding shaft 400. The grounding shaft 400 abuts against the locking rod 200, so that the grounding shaft 400 can limit the locking rod 200 to prevent the locking rod 200 from rotating, causing the locking rod 200 to move along the axial direction of the locking rod 200 in a direction away from the rod 3 to be grounded, resulting in the locking rod 200 being unable to lock the rod 3 to be grounded.

[0040] During specific implementation, the grounding shaft 400 moves along the extension direction of the second connecting hole 120 toward the direction away from the locking rod 200 to avoid the locking rod 200, ensuring that the locking rod 200 rotates around the axis of the locking rod 200 and moves along the axial direction of the locking rod 200 toward the direction close to the first connecting hole 110, until the locking rod 200 abuts against the grounding rod 3, the grounding shaft 400 moves along the extension direction of the second connecting hole 120 toward the direction close to the locking rod 200, so that the grounding shaft 400 abuts against the locking rod 200.

[0043] Specifically, the second barrel section 102 is used to install the detection alarm component 300 , and the first barrel section 101 is used to install the grounding shaft 400 and the rod to be grounded 3 , so that the detection alarm component 300 can detect the charge on the rod to be grounded 3 .

[0044] In this embodiment, the low-voltage circuit breaker grounding wire quick access auxiliary connector also includes a first cylindrical structure 500, the second cylindrical section 102 is inserted into the first cylindrical structure 500, the axial end face of the first cylindrical structure 500 is abutted against the axial end face of the first cylindrical section 101, and an installation groove 510 is provided on the circumferential outer surface of the first cylindrical structure 500, and the installation groove 510 is used to install the detection alarm component 300.

[0045] Specifically, the detection alarm component 300 is installed through the installation groove 510, so that the detection alarm component 300 is connected to the first cylindrical structure 500; the second cylindrical section 102 is inserted into the first cylindrical structure 500, and the axial end face of the first cylindrical structure 500 abuts against the axial end face of the first cylindrical section 101, so that the joint body 100 and the first cylindrical structure 500 are connected, and then the detection alarm component 300 is connected to the joint body 100.

[0046] In this embodiment, the low-voltage circuit breaker grounding wire quick access auxiliary connector also includes a second cylindrical structure 600, which is sleeved on the second cylindrical section 102 and at least part of the locking rod 200, and the circumferential outer wall of the second cylindrical structure 600 is connected to the circumferential inner wall of the first cylindrical structure 500, and the second cylindrical structure 600 is threadedly connected to the locking rod 200.

[0047] Specifically, the second cylindrical structure 600 is threadedly connected to the locking rod 200, so that the second cylindrical structure 600 can convert the rotation of the locking rod 200 into linear motion, ensuring that the locking rod 200 can move along the axial direction of the locking rod 200 while rotating; at the same time, the second cylindrical structure 600 is sleeved on the second barrel section 102 and at least part of the locking rod 200, thereby strengthening the connection between the second barrel section 102 and the locking rod 200.

[0048] In this embodiment, the locking rod 200 includes a first rod segment 201 and a second rod segment 202 which are connected to each other. The flow cross-sectional area of ​​the first rod segment 201 is larger than the flow cross-sectional area of ​​the second rod segment 202. The second rod segment 202 is inserted into the joint body 100. A first thread is provided on the circumferential outer wall of the first rod segment 201, and a second thread is provided on the circumferential inner wall of the second cylindrical structure 600. The first thread and the second thread are matched.

[0049] Specifically, the first rod segment 201 is used to thread the locking rod 200 to the second cylindrical structure 600 , and the second rod segment 202 is used to abut against the rod to be grounded 3 , so that the locking rod 200 limits the position of the rod to be grounded 3 .

[0050] In this embodiment, the low-voltage circuit breaker grounding wire quick access auxiliary connector also includes a turning handle 700, which is connected to one end of the locking rod 200. The turning handle 700 is rotatably arranged around the axis of the locking rod 200, so as to drive the locking rod 200 to move along the axial direction of the locking rod 200 toward the direction close to the first connecting hole 110 through the turning handle 700 until the other end of the locking rod 200 abuts against the grounding rod 3.

[0051] Specifically, the locking rod 200 is driven to rotate by the turning handle 700, so that the locking rod 200 can move along the axial direction of the locking rod 200, which is convenient for the user to drive the locking rod 200 to rotate by holding the turning handle 700, thereby improving the convenience of quickly connecting the auxiliary connector of the low-voltage circuit breaker grounding wire.

[0052] In this embodiment, the handle 700 includes a first handle barrel section 701 and a second handle barrel section 702 which are connected to each other. The handle 700 extends along the axial direction of the locking rod 200. The flow cross-sectional area of ​​the first handle barrel section 701 is greater than the flow cross-sectional area of ​​the second handle barrel section 702. The circumferential inner wall of the second handle barrel section 702 is connected to the locking rod 200.

[0053] Specifically, the second handle barrel section 702 is used to connect the handle 700 and the locking rod 200, and the first handle barrel section 701 is used for the user to hold.

[0054] In this embodiment, the axial end wall of the second handle barrel section 702 is rotatably connected to the axial end wall of the second tubular structure 600 , and the axial end wall of the first handle barrel section 701 is rotatably connected to the axial end wall of the first tubular structure 500 .

[0056] In specific implementation, there are four low-voltage circuit breaker grounding wire quick access auxiliary connectors, and the four low-voltage circuit breaker grounding wire quick access auxiliary connectors are firmly connected to the A phase, B phase, C phase, and neutral line terminal of the low-voltage circuit breaker through the grounding rods.

[0058] The low-voltage circuit breaker grounding wire quick access auxiliary connector of the present invention includes a connector body 100, a locking rod 200 and a detection alarm 300. The locking rod 200 moves along the axial direction of the locking rod 200 toward the direction close to the first connection hole 110 to abut against the rod 3 to be grounded, so as to prevent the rod 3 to be grounded from rotating and causing the rod 3 to be grounded to fall out of the first connection hole 110, thereby ensuring that the rod 3 to be grounded and the connector body 100 are fully electrically connected, thereby ensuring that the rod 3 to be grounded and the external grounding component are electrically connected, and avoiding the rod 3 to be grounded from having grounding failure, thereby solving the problem of low-voltage circuit breakers in the prior art being prone to grounding failure. At the same time, the detection alarm 300 detects the real-time voltage of the rod 3 to be grounded without contacting the rod 3 to be grounded, and issues an alarm when the real-time voltage is detected to be greater than the safety voltage, thereby preventing the connector body 100 from being electrically connected to the charged rod 3 to be grounded, and avoiding safety accidents.

[0059] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0060] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of this application.

For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
